Islamabad, Pakistan - Five people arrested in Pakistan had been reported missing in the United States, and police are confident they were planning terrorist acts, a Pakistani police official told media.

It is too soon to link the men with any terrorist organizations, said Tahir Gujjrar, deputy superintendent of police in Sargodha, Pakistan, but preliminary investigations suggest they had sought to link up with the Jaish-e-Mohammed and Jamaat ud Dawa militant organizations. Neither group showed interest, however, Gujjrar said.

The five were from Virginia and their families had contacted the FBI soon after they went missing, he said. They include two Pakistani-Americans, two Yemeni-Americans and an Egyptian-American.

The arrests came after a raid on a home in Sargodha, about 120 miles south of Islamabad, Gujjrar said.
